1/4c onion, chopped ( I love onion so I added more, you may like less...)
juice of 1/2 a lime (this is so the avocado doesn't turn brown)
2-3 sprigs of cilantro (you can substitute with basil if you don't like cilantro)
salt and pepper, to taste
Cook the chicken breast whole. When cooked thoroughly, dice it up in bite size pieces.
Mash the avocado until a creamy consistency. Add the onion, cilantro leaves, lime juice, salt and pepper. IF the chicken is cool, blend it into the mixture. Don't mix the warm chicken in, you don't want to "cook" the avocado.
Place in refrigerator until completely cool, then ENJOY!
This would taste fabulous on croissant, but to keep things low fat, I'm simply enjoying by itself.
